NASA developed and tested a 3D-printed antenna to demonstrate a low-cost capability to communicate science data to Earth. The ...

NASA 3D prints antennas - controlling electromagnetic and mechanical properties - for space-to-Earth communication using a Fortify printer.

Read The 3D-printed antenna mounted to a ladder prior to testing at NASA's Columbia Scientific Balloon Facility in Palestine ...

"For each p-bit encoding pattern modulated into the programmable metasurface, the metasurface antenna will generate a corresponding radiation pattern," said Cui. "Out of the 2 p possible patterns, 2 p ...

The secondary (false) glideslope generally appears above the primary (real) one. Various radiation patterns from the antenna or other objects combined with the ground reflection of the transmitted ...

Add a description, image, and links to the antenna-pattern topic page so that developers can more easily learn about it.

Abstract: This letter presents an effective spherical far-field extrapolation and reconstruction method for antenna measurements. The proposed method firstly uses geometric relationship to project the ...
